After familiar targets of ending summer, I had my second go at this subject. My first try was a disaster, with the alt-az preventing subs long enough to capture useful signal; The EQ being more stable (despite bad PA) I could extend subs to catch this more satisfying result.
Making progress, more subs to be added later.
